Question

If you have an initial water level in a graduated cylinder of 17 mL, and the final water level after placing a 2g aluminum piece in is 20 mL, what is the density of the aluminum in g/mL?

Formula:? Work:? Answer:?

Answer 1

0.67g/mL

Step-by-step explanation:

The formula is [ d = m/v ] where m = mass and v = volume

Find the volume.

20 - 17 = 3

Find the density.

d = 2/3

d ≈ 0.67

Best of Luck!

Answer 2

The answer is

0.67 g/mL

Step-by-step explanation:

The density of a substance can be found by using the formula

`density = (mass)/(volume) \\`

From the question

mass of aluminum = 2 g

volume = final volume of water - initial volume of water

volume = 20 mL - 17 mL = 3 mL

The density is

`density = (2)/(3) \\ = 0.6666666...`

We have the final answer as

0.67 g/mL

Hope this helps you
